Communication terminal and communication switching method

A switch instruction is transmitted from a PC terminal (105) to a portable PC terminal (107) (S302); the portable PC terminal (107) transmits a switch connection request to a portable communication terminal (102) on the other end of communication (S306); the portable PC terminal (107), when it is waiting for a response to the switch connection request and receives a switch connection request from the other end of communication, detects that switching processes are being performed simultaneously (S312); upon detection of the simultaneous switching, a switching session related to either switch connection request is determined to be continued (S314 and S315); the portable PC terminal (107), which received the switch connection request to which the switching session determined to be continued was related, transmits a success response including information on the switching process of the portable PC terminal (107) side (S316 and S319); and the PC terminal 101, which received the switch connection request to which the one to be stopped was related, transmits a failure response (S317 and S318). This allows switching to be carried out with quick and not many procedures in both end communication terminals performing multimedia communication with each other.

Chinese environment-oriented complex scene text positioning method

The invention discloses a Chinese environment-oriented complex scene text positioning method, which mainly solves the problem that scene text positioning in a complex background has a high false alarm rate in the prior art. In the method, the advantages of an edge-based text positioning method and a texture-based text positioning method are combined, and edge features and texture features are combined by stages. The method comprises the following steps of: detecting a text area by using the edge features, namely performing edge extraction and binarization processing on a down-sampled color image, connecting the edges of characters to form a block through morphological operation, extracting the features of each communicated domain, and removing a great number of non-character communicated domains by using a cascaded threshold classifier to acquire candidate character communicated domains; and extracting the texture features of the candidate character communicated domains, and further judging whether the candidate character communicated domains are character communicated domains or not by using a back propagation (BP) network classifier. The method has the advantages of high text positioning accuracy and high speed under the conditions of complex illumination and backgrounds, and can be used for text automatic extraction and identification in a complex scene.

Conversation maintaining method and device

The invention provides a conversation maintaining method and device. According to the conversation maintaining method and device, a conversation maintaining identification is set for a client side through load balancing equipment, the conversation maintaining identification is sent to the client side through an HTTP redirected response message which contains the conversation maintaining identification, the client side carries a conversation maintaining message in a subsequent HTTP request message, the load balancing equipment sends the HTTP request message to a corresponding server according to the correspondence between the conversation maintaining identification which is locally stored and servers so that HTTP request messages containing the same conversation maintaining identification can be sent to the same server, then conversation maintaining is achieved, and the server sends an HTTP response message to the load balancing equipment after receiving the HTTP request message. According to the conversation maintaining method and device, due to the fact that the HTTP response message can be directly transmitted to the client side by the load balancing equipment, the correspondence between the conversation maintaining identification and the server can be obtained without the need of analyzing each HTTP response message sent by the server. Accordingly, burden of the load balancing equipment is relieved, and processing capacity is improved.

System for omnidirectionally monitoring health and actions of old people

The invention relates to a system for omnidirectionally monitoring health and actions of old people, mainly comprising a plurality of parts, such as a human body posture monitor, a health characteristic collector, a signal transmission device, a locating system, an automatic alarming device and a signal processing system and the like, wherein the human body posture monitor, the health characteristic collector and the signal transmission device are carried with the old people. The human body posture monitor and the health characteristic collector which are carried with the old people are in touch with the signal processing system through the signal transmission device; various types of postures of the old people are simulated and reproduced on a computer; and health situations of the old people are recorded and stored in an information manner. The locating system monitors the locations of the old people who have activities outdoors. When the posture monitor detects that the old people have dangerous actions, such as tumbling and the like, or the health characteristic collector collects abnormal health characteristics of the old people, the automatic alarming system starts and emits an alarm to the family or an emergence centre. The system provided by the invention is mainly used for monitoring the health of the old people in real time and helping single old people to give an alarm in case of sudden illness or accidents.

Vehicle lane charging assisting system
